1. 10.6 Three- Dimensional Figures I can name three-dimensional figures

2. Vocabulary polyhedron cylinder face pyramid edge cone vertex sphere prism base

3. A polyhedron is a three-dimensional object with flat surfaces, called faces, that are polygons. When two faces of a three-dimensional figure share a side, they form an edge. A point at which three or more edges meet is a vertex (plural: vertices).

4. 5 faces 8 edges 5 vertices 7 faces 15 edges 10 vertices Identify the number of faces, edges, and vertices on each three-dimensional figure. A. B.

5. 6 faces 12 edges 8 vertices 5 faces 9 edges 6 vertices Identify the number of faces, edges, and vertices on each three-dimensional figure. A. B.

6. A prism is a polyhedron with two congruent, parallel bases, and other faces that are all parallelograms. A prism is named for the shape of its bases. A cylinder also has two congruent, parallel bases, but bases of a cylinder are circular. A cylinder is not a polyhedron because not every surface is a polygon.

7. A pyramid has one polygon-shaped base and three or more triangular faces that share a vertex. A pyramid is named for the shape of its base. A cone has a circular base and a curved surface that comes to a point. A sphere has no base and one curved surface. All points on the surface are the same distance from a point called the center of the sphere.

8. The figure represents a cylinder. Name the three-dimensional figure

9. The figure is a rectangular prism. Name the three-dimensional figure represented by the object.

10. The figure is a square pyramid. Name the three-dimensional figure represented by the object.
